## What

Display Mercurial information when in a Mercurial repository. For maximum compatibility,
make sure your `hg` executable is up-to-date (when branch or status information is incorrect for example).

## Sample Configuration

import Config from "@site/src/components/Config.js";

<Config
  data={{
    type: "mercurial",
    style: "powerline",
    powerline_symbol: "\uE0B0",
    foreground: "#193549",
    background: "#ffeb3b",
    properties: {
      newprop: "\uEFF1",
    },
  }}
/>

## Properties

### Fetching information

As doing Mercurial (hg) calls can slow down the prompt experience, we do not fetch information by default.
You can set the following properties to `true` to enable fetching additional information (and populate the template).

| Name             | Type                | Description                                                                                                                                                                                                                                                                                 |
| ---------------- | ------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `fetch_status`   | `boolean`           | fetch the local changes - defaults to `false`                                                                                                                                                                                                                                               |
| `status_formats` | `map[string]string` | a key, value map allowing to override how individual status items are displayed. For example, `"status_formats": { "Added": "Added: %d" }` will display the added count as `Added: 1` instead of `+1`. See the [Status](#status) section for available overrides. Defaults to an empty map. |

## Template ([info][templates])

:::note default template

```template
hg {{.Branch}} {{if .LocalCommitNumber}}({{.LocalCommitNumber}}:{{.ChangeSetIDShort}}){{end}}{{range .Bookmarks }} \uf02e {{.}}{{end}}{{range .Tags}} \uf02b {{.}}{{end}}{{if .Working.Changed}} \uf044 {{ .Working.String }}{{ end }}
```
